   CONCERNING...SEVERE THUNDERSTORM WATCH 324...
   
   VALID 222044Z - 222145Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 324
   CONTINUES.
   
   NUMEROUS THUNDERSTORMS ARE SPREADING EASTWARD ACROSS WW 324 AND WILL
   APPROACH THE EASTERN EDGE OF THE WATCH IN THE NEXT 1-2 HOURS.  A NEW
   WW WILL BE CONSIDERED FOR A NARROW AXIS FROM WRN WV INTO WRN NC.
   
   WIDESPREAD THUNDERSTORMS...INCLUDING SCATTERED SEVERE STORMS HAVE
   BEEN OCCURRING THIS AFTERNOON OVER MUCH OF CENTRAL/EASTERN KY AND
   TN.  THESE STORMS WILL BE MOVING OUT OF THE WATCH IN THE NEXT COUPLE
   OF HOURS...AND INTO THE HIGHER MOUNTAINS OF EASTERN TN AND WRN
   WV/VA/NC.  STRONG DAYTIME HEATING HAS OCCURRED OVER THIS
   REGION...ALLOWING AIR MASS TO BECOME MODERATELY UNSTABLE.  WHILE LOW
   LEVEL FORCING MECHANISMS ARE QUITE WEAK...NUMEROUS OUTFLOWS FROM
   STORMS TO THE WEST MAY CONTINUE TO PROMOTE INTENSE THUNDERSTORM
   DEVELOPMENT FOR A FEW MORE HOURS.  SUFFICIENT WESTERLY FLOW ALOFT
   WILL MAINTAIN A RISK OF ORGANIZED MULTICELL OR OCCASIONAL SUPERCELL
   STORMS CAPABLE OF HAIL AND DAMAGING WINDS.
